Parallel flow condenser for electric automobile heat pump system

Abstract

The invention discloses a parallel flow condenser for an electric automobile heat pump system. The parallel flow condenser comprises a left flow collecting pipe assembly (1) and a right flow collecting pipe assembly (2) which are arranged in parallel, a plurality of parallelly-distributed flat pipes (4) are arranged between the left flow collecting pipe assembly (1) and the right flow collecting pipe assembly (2), and the two ends of the flat pipes (4) are connected with the left flow collecting pipe assembly (1) and the right flow collecting pipe assembly (2); and the right flow collecting pipe assembly (2) is further provided with an air inlet pipe assembly (6), a thermal expansion valve (7), an inlet and outlet assembly (8) and a liquid discharging pipe assembly (9), and the thermal expansion valve (7) is connected with the inlet and outlet assembly (8). A traditional condenser can have the function of an evaporator through the parallel flow condenser of the special structure, an evaporator does not need to be additionally arranged in an automobile heat pump system to gasify a refrigerant, the cost can be reduced, and the area, occupied by an air conditioning system, of the interior of an automobile forecabin can be decreased.

Description

technical field [0001] The invention relates to the field of automobile air-conditioning heat pump systems, in particular to a parallel flow condenser for electric automobile heat pump systems. Background technique [0002] While fuel vehicles bring convenience to people's lives, they also bring about two major problems: energy consumption and environmental pollution. Compared with fuel vehicles, electric vehicles have the advantages of zero emission, no pollution, low noise, and high energy efficiency. Like fuel vehicles, electric vehicles also need to create a comfortable driving environment, that is, they must be equipped with corresponding air-conditioning systems to improve their comfort and competitiveness. At the same time as development and development, it is also necessary to develop the supporting air conditioners at the same time . [0003] Electric vehicles are powered by on-board power supply, and the wheels are driven by motors. There is no engine waste heat f...

AI Technical Summary

Problems solved by technology

[0003] Electric vehicles are powered by on-board power supply, and the wheels are driven by motors. There is no engine waste heat for heating in fuel vehicles, so the heating system of fuel vehicles cannot be used. Existing fuel vehicles usually use PTC electric heaters or fuel heaters for heating. , but these heating devices are usually expensive, heavy and inefficient, which is not conducive to widespread promotion. Therefore, it is necessary to develop a heating system that can be widely promoted and is suitable for electric vehicles
